Perplexity

Portable Computer is the on-device version of Perplexity's agent platform, Perplexity Computer, aimed at people who want an AI agent to plan and run multistep work without pushing sensitive files to the cloud. This launch brings it to Windows PCs equipped with NVIDIA GeForce RTX and RTX PRO GPUs with 24GB or more of VRAM , extending an earlier rollout that began on NVIDIA DGX Spark systems and RTX PCs running Linux . For founders and operators who have been curious about local agents but did not want to assemble the stack themselves, it lowers the setup barrier considerably. Under the hood, the app ships with a local model such as Qwen 3.8 27B that is post-trained to work with Perplexity Computer and optimized for NVIDIA RTX GPUs , so users do not have to pick weights or wire up inference tooling. The harness runs the agent loop on device, with connectors for Microsoft Outlook, OneDrive, Word, Google Drive, Gmail, Slack and GitHub so it can act across the tools people already use. When a task calls for more advanced reasoning, Portable Computer can identify that it needs cloud support and ask the user for permission before sending information off-device , which keeps the local-first default intact while leaving frontier models available on demand. The launch matters now because agent workflows have been gated by cloud costs and privacy concerns, particularly for finance, legal, and engineering tasks that touch regulated or proprietary data. Locally completed work does not consume Perplexity Computer credits , which changes the economics for anyone running long or repeat jobs, and it gives Windows users on capable RTX hardware a practical way to test whether a private agent can replace parts of their existing SaaS workflow.
